Default coolant light

The coolant warning light has begun to flash whenever I take a corner or accelerate moderately hard. The fluid level and concentration is fine and there are no leaks. Any ideas?

'87 4KQ

Default I have the same problem!

They have told me that the coolent level must be low or the sensor is bad. I have not had a chance to attempt to fix the sensor but I have verified my coolent level is correct.

My car is an '84 4KqCS

I had the same issue, and here is what I did when I finally got sick and tired of looking at the flashing light:

Unplug the coolant sensor and see if that has any effect. Hot wire the plug and, again, see if that has any effect. If not, then replace the temp sender on the top of the coolant pipe that the upper rad hose connects to. That should lick the problem

I had the same problem, I unscrewed the sensor a little to allow air to escape, and let out any possible air bubbles, that worked for awhile, but just this week the darn thing started doing it again, i will post it, if i decide to go get a new sensor, if that fixes it for good, its pretty aggrevating,JP
